Well, I'm an Independent Magical Consultant. That can get me in trouble with full-awakened, and i carry the gun for self-defense, as it's stated in the License. Usually magical threats are hard to stop with even a heavy pistol, so it's plausible and reasonable. Also, broadcasting his data openly means he can get legal, semi-legal, or entirely illegal work any time, if someone notices it, or looks for someone to help with Awakened matters.
As for his Awakened status, for now he worked in the Barrens - he got the SIN and License recently, and he didn't really know where he was going, so he's not fully prepared. A nosy mage can look at his aura and notice it's stronger than it should be for an 'Peeping Tom' adept. And the spell he's sporting at the moment would give him away instantly. He just didn't think of it yet.
